Grim,

hate to ask another bulb selection question but here goes. I have a 90 gal with 6 54w T5 over it. My tank is a combination of SPS and LPS and I am looking for the best color from my corals obviously. Currently I am running all Geisman 2 pure actininc 2 aquablue+ and 2 atinic + and am getting good color but I am not getting the pop I like especially in the red spectrum. My water quality is excellent I do 15 gallons water changes weekly and 25-30 gallons every 4th week. I am dripping Kalk and all other chemistry issues are in good shape as is temp. What do you recommend I change to optimize my colors?

A GE 3000k bulb gives lots of pop in the red area. A 6500k is also an option.
